[Presence of lymph-vascular anatomical units in dermoid cysts and the probable existence of a local immune defense system in various tissues].
Studies on tooth eruption in several ovarian dermoïd cysts showing the existence of immune defense gingival structures has allowed the presence of similar structures associated with respiratory and digestive differentiation zones to be observed. These structures are formed of histiocyto-plasmocyto-lymphocytes associated with capillary loops. The origin and histogenesis of those structures remains to be clarified but they suggest the probable existence of localised immune defense systems within certain tissues.
